(See the infographic below for details of the Dáil's historic nature)
The most significant change that is to take place in this new Dáil is a shift in the positioning of each of the three main parties.
Fianna Fáil loses the title of largest party, which it has held without interruption since 1932, falling dramatically to third in terms of size. In fact the party now has the lowest number of Dáil seats in its history, less than half the amount of its next worst performance in 1927.
On the other end of the scale Fine Gael is the largest party in Dáil Éireann for the first time in its 78-year history. As part of this the party has also recorded its highest seat tally ever, besting its previously-held record by six.
Labour also enjoys its biggest Dáil representation ever, beating the 1992 'Spring Tide' by a comfortable margin. The party is now the second biggest in the Lower House, another historic first.
Sinn Féin, a party that until now would have been considered 'small', has nearly three times as many seats as its previous best of five. This puts the party fourth in terms of size, marking an impressive growth from seventh largest in 1997.
Of the remaining parties The Socialist Party has two TDs for the first time while the 31st Dáil marks a parliamentary debut for the People Before Profit Alliance. As for the Independent TDs they too play their part in this historic Dáil, simply because there has not been as many of them in there since 1927.
Also historic in its absence is The Green Party, which is without a TD for the first time in 22 years.
However not all of the new House's historic elements are party-related.
There are 25 female members the 31st Dáil - the highest figure ever reached even if it does represent just 15% of all TDs. In addition to this the majority of the new Dáil's TDs were not even present in the last one, while 76 of them have never been TDs before.
Most of these new TDs come from Fine Gael and Labour which, as a coalition, will hold 113 of the 166 seats. This will give them a far greater majority than any government has held since the State's foundation.
